Hi team, I am running a performance testing project on Hololens2 with the latest 2022.3.18f1, and it looks like some update from the {{xr.management}} package breaks the project. In UnityPlayer.log I got:
Initialize engine version: 2022.3.18f1 (d29bea25151d)
The referenced script (Unknown) on this Behaviour is missing!
The referenced script on this Behaviour (Game Object '<null>') is missing!
A scripted object (probably ?) has a different serialization layout when loading. (Read 48 bytes but expected 76 bytes)
Did you #ifdef UNITY_EDITOR a section of your serialized properties in any of your scripts?
The referenced script (Unknown) on this Behaviour is missing!
The referenced script on this Behaviour (Game Object '<null>') is missing!
XRGeneral Settings awakening...
UnityEngine.DebugLogHandler:LogFormat(LogType, Object, String, Object[])
UnityEngine.Logger:Log(LogType, Object)
UnityEngine.Debug:Log(Object)
UnityEngine.XR.Management.XRGeneralSettings:Awake()

The project is a private repository provided by Microsoft to collect performance matrices for Hololens2, please direct message me for the entire project; the attachment is the full player log.
